This will show the default host on many servers, thus making it easy to detect various software on the server or even perform a DoS attack against the server. On this server all requests to the default host lead to an empty file.

Another interesting part was a user agent. I never saw such thing before. Searching the Internet revealed that it is some kind of vulnerability scanner. Good to know. Now it is in my mod_security rules too.

If you are curious what is "toata dragostea mea pentru diavola", it is Romanian. It means approximately "All my love is for the devil".
